T 00% whom it may concern.-

Be it known that I, GEORGE M. WoLooTr, a citizen of the United States ofAmerica, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements inLubricators, of which the following is a specification, reference beinghad therein to the accompanying drawings- This invention relates toimprovements in lubricators and more especially to hydrostaticlubricators especially adapted for use upon locomotives and other highpressure engines; and the objects of the invention are to provide alubricator of this class which is simple in construction, efficient inits operation, and not liable to get out of order or become clogged, andif such a contingency does happen, may be readily taken apart forcleaning or repair.

It is also an object of the invention to provide the same with a seriesof sight feeds of the bullseye type which are not liable to be broken bythe steam pressure and to arrange these sight feeds in a position wherethey are exposed to the light on all sides and where the engineer mayconveniently look directly through all of them at once and determinetheir operation at a glance, the arrangement also being such that theyare not affected by the heat from the boiler which tends to cloud theglasses.

A further object of the invention is to provide a device having theseveral advantages of the peculiar construction, arrangement andcombination of parts all as hereinafter more fully described and shownin the accompanying drawing, in which Figure 1 is a side elevation of adevice embodying the invention; Fig. 2 a central vertical sectionthrough the same; Fig. 3 a horizontal section on the lines 00-51; ofFigs. 1 and 2; Fig. 4 is a detail showing in section one of the sightfeeds and the connected casing of the next one below.

As shown in the drawings 1 is a suitable cylindrical body forming an oiland water chamber and 2 is a steam dome forming a condensing chamberseparated from the oil chamber by a horizontal wall 3.

1 is a screw-threaded stud upon the back of the body for supporting thelubricator adjacent to the boiler front or in any other convenientposition, and 5 is a steam supply pipe opening into the top of the steamdome to supply steam thereto.

A passage 6 shown in dotted lines in Fig. 2 is formed in the dividingwall 3, which passage is controlled by a needle valve 7, and a tube orpipe 8 leads from said passage downward to near the bottom of the oilchamber or reservoir to conduct the water of condensation from the upperinto the bottom of said lower chamber.

Cast integral with the forward side of the body is a series ofcylindrical shaped casings 9 arranged one above the other in a verticalrow with their lengths extending transversely of the body in ahorizontal position, and each of these casings is connected to the onebelow by a connecting neck portion 10 and the series is connected to thebody and spaced therefrom by arms 1 1 formed integral with the body andthe neck portions. Each of these cylindrical casings is bored inwardfrom each end forming shoulders 12 against which are seated the innerends of the solid cylindrical glasses 13 with thin copper rings 14interposed between and the outer ends of the bores are of greaterdiameter than they are adjacent to the shoulders and are internallyscrew-threaded to receive the bushings 15 which are screwed in against asuitable packing 16 with a soft metal ring 17 interposed between thepacking and the end of the bushing. Each bushing is formed with ahexagonal head by means of which it is turned in and is provided with aninwardly projecting shoulder 18 to engage a shoulder formed by a reducedouter end 19 on the glass which projects outward in the opening in thebushing, the edge of which opening is rounded off so as not to obstructthe view through the glasses.

The neck portions 10 connecting the cylindrical casings of the bullseyesight feeds, are bored vertically through from end to end of the seriesand the outer ends of this bore 20 are closed by screw plugs 21 and thecommunication through this bore between the easings is closed off byscrew plugs 22 in the neck portions midway between the casings orsights. Leading from the bore 20 in the neck portions directly aboveeach plug and inward through each of the arms 11 is a small oil inletpassage 23 into the inner ends of which passages within the reservoirare secured tubes 24 extending upwardly in the body or reservoir to nearthe upper end or wall 3, and screwed into internally screwthreadedbosses projecting outward from the neck portions, and extending acrosssaid bore into the ends of said oil passages are the nee- IIO acontinuation of said passage formed in an inwardly projecting rib 28 onthe side of the body and across the upper end of said body through aportion of said. passage formed in a bridge bar 29 to a discharge arm 30screwed into a socket provided therefor at the back side of the body,which. arm is connected by a tallow pipe (not shown) in the usual mannerwith the righthand cylinder of the locomotive. The next nipple or thatof the middle sight feed of the series discharges upward. and through apassage 31 extending inward through the arm 11, upward through a rib inthe body similar to the rib 28 and thence across the upper end of thebody through a bridge bar 32 near the opposite side of the body to thatnear which the other bridge bar extends, to a discharge arm similar tothe arm 30, which arm is connected to the left cylinder of thelocomotive in the same manner as the other arm. The nipple of the uppersight feed discharges into a passage 33 extending inward through the arm11 and across the body through the bridge bar 32 to its discharge arm 30which is connected to the air pump.

In each neck portion 10 is formed a duct or assage 34 opening into theinterior of each bullseye at one side of its nipple and extendingdownward and outward through the side of the neck where it is closed bya valve stem 35 having a square head by means of which it may be turnedin or out and open the passage to permit the contents of the bullseye tobe blown out to clean the same.

Pressure equalizing tubes 36 are rovided within the'condensing chamberanc extend vertically upward therein with their upper open ends near thetop of said chamber, their lower ends being secured within holes 37 inthe dividing wall between said chamber and the reservoir, which holesopen into the oil assages 27, 31 and 33 as indicated in dotted ines inFigs. 2 and 3. These tubes are thus inclosed within the chamber andconnect the upper part of the condensing chamber with the oil dischargepassages in the most direct manner to conduct live steam thereto andeffectually equalize the pressure. By arranging the sight feeds in avertical row, they may all be placed at the forward side of thelubricator body where they are protected from the heat of the boiler andby arranging them in horizontally extending casings supported. atadistance from the body, they are in a position where the engineer andfireman has an unobstructed view of them and being exposed to the lightat both ends their operation may be seen without difficulty.

Having thus fully described my invention what I claim is 1. In ahydrostatic lubricator, the combination with a reservoir forming thebody of the lubricator, of means at the rear side of the reservoir forsupporting the lubricator, and a series of sight feeds arranged in avertical row and supported at the forward side of the reservoir andcommunicating with the interior thereof to receive oil therefrom.
